to produce a multi-record machineoperating Belt known that we, CHARLES Tnoim; and. WALTER TnoMA, citizens of the United States of America, and residents of Carlstadt;

' Bergen county, and State of. New. Jersey,

have-invented certain new and useful Imrovements in Phonographs, of which the 'ollowing is a specification,

The present-invention relates to. phonographs or other sound reproducing machines;

has more particularly reference to' amulti-record ora repeater phonograph; A

In machines of this character, the record,- or the sound reproducing lmechanism, is given a reciprocatmg motion, one with relation to the other; .Une moter being utilized toeiiect the iorwardfeed or outward .excur sion during the sound. reproducing period,

and another motor, generally a "spring or a weight, is utilizedfto original position at a-greater speed than that attained during the outward excursion.

The chief object of the present invention is automatically, and the invention consists "ofthe hereinafter described features of conthe. direction of the arrow 2 in Fig. .1, showstructionas pointed out in the claims. 1 In the accompanying drawings theinvention is embodied in a concrete and preferred form, bu't changes of construction may be made without departing from. the legitimate and intended scope of the invention. I In the said drawings-z Figure 1 is a plan view of a phonograph embodying the invention. Fig. 2 is an end elevation looking in ing the stylusdisengaged from the record Fig. 3 is a vertical sectlonal view on the line 3-3 of Fig. 1 showing the stylus in engagement with the record. Fig. 4 is .a detail view of the double reversely'threaded repeater screw. Fig. 5 is a vertical sectional .view on the line 55 in Fig. 1. Fi .6 is a.

.be forced out of engagement 'Patented Dec. 1'2, 180? with the feed screw during the sound repro ducing period andhavingthe st g 'lus 7 adapted to engage with the record.

8 indicates the repeater screw threads are ,coars er than those of the feed 5 screw. This repeater screw is provided with one thread'QeXtendm substantially throughout its entire .lengt and with a reverse thread 16 extending only a short distance of its length and 'rovided with a trip 11. Mounted on the racket 120i the sound re.,

' producing mechanism is a link 13 provided with the boat shaped thread follower 14iad-a ted to engage in the threads or the dou 1e reverse threaded repeater screw 8.

Pivotally connected to the link 13 is an arm 14* which has another pivotal support on the rod 15 located underneath the repeater screw and on which the said armis adapted to slide. Mounted on the drive shaft 2 is a trip 16 7 which is adapted to engage with the nose 1? of the arm 14* when broughtinto the plane thereof.

'1 8 den0tes a shaft on which is mounted the The other hub section 21 normally tends to with the spin dies 22 b reason of the spring 23 but is confined an held in contact with the-said spindles by reason of the cam nut 24 engaging with the cam surface 25 on the hub section. By turnin the cam nut 24 the spring 23 will be allows to press the hub section 21 out of engagement with the spindles 22, and by turning the arms (if the said hub section to a point where they will be in between the records, the latter can be removed ,from th e spindles and replaced by others.

26 indicates a slot in the hub section 21 I adapted to receive the pin 27 on the shait 18 'so as to insure the hub section 21 being returned'to its proper position cireuinferen- ,ieo

tially when it isftightened u against the spindles 22. Loosely mounts on the shaft 18 is a cam collar 28 having the' awl 29 held in position by the s ring 30 an adapted to engage with the teet of the ratchet 31 when 105 turned in one direction and to move idly over the teeth when turned in the other direction. The ratchet 31 is fixed on the shaft 18 by means of the pin 32.

36 is a pin carried by the sound reproduc- 11,0

g mechanism adapted to engage with the cam collar 28.

On the end of the drive shaft 2 is a friction disk 33 held yieldingly in position by means of a spring 34. One end of each of the spin- '(lles 22 is rovided with a complementary friction dis 35 adapted to engage with the feed screw 33 when brought into alinement therewith, the spring 34 allowing the two dlsks to slip into engagement with each other.

Motion is imparted to the device by means of a suitable'motor from which ou er is transmitted to the pulley 37 on t 1e drive shaft 2, and for the purpose of this disclosure *the said pulley 37 may be considered the motor. indicates a gear mounted onthe end of the shaft 2 and int-ermeshing with the gear 39 on the end of the repeater screw.

The operation is as follows :Assume that the sound reproducing mechanism is traveling in a forward direction during the sound reproducing period and that the thread follower is in engagement with the feed screw 3 and the stylus 7 in engagement with the record 40. As the sound reproducing mechanism reaches the limit of its movement in a forward direction the nose 17 on the arm 14 willvbe brought into the plane of the trip 16 on the feed screw shaft. This will cause the link 13 to be swung around its pivot on the sound reproducing mechanism whereby the boat shaped follower 14 will be brought into engagement with the thread 9 of the repeater screw, at the same time causing the said reproducing mechanism to be turned on the shaft 4 and lifting the thread follower 6 out of engagement with the feed screw 3 and the stylus 7 out of engagement with the rec ord. By this means the sound reproducing mechanism will be moved back to its initial position, but at a greater speed than the speed of its outward excursion. hen the follower 14 reaches the extreme end of the thread 9 it will come into contact with the surface 41 causing the said follower to be turned around its swivel point 42 and to engage in the thread 10 of the repeater screw. By this means the motion is reversed and the sound reproducing mechanism is moved forward; again but at a. greater speed than the speed attained during the sound re roducing period. This forward motion wil continue until the follower 14 encounters the trip 11 which will cause the link 13 to swing around its pivot on the sound reproducing mechanism thereby disengaging the follower from the shaft 8 and allowing the said reproducing mechanism to descend and the thread follower 6 to be brought into contact with the feed screw 3 and the stylus into engagement with the record. In this way .the same record may be repeated several times. If, however, the pin 36 is in position on the sound reproducing mechanism it will during the return movement of the said sound reproducing.

mechanism, enter the groove of the cam col- 43 denotes a guideway on the framework adapted to support the projection 44. of the sound reproducing mechanism when the st lus is in engagement with the record, so as to relieve the latter of the weight of the said reproducing mechanism.

45 is a lever having the cam surface 46 whereby the stylus can be raised out of engagement with the record at will.
